Its comprehensive utilization in agriculture showed a significant effect on control of soil alkalization, amelioration of solonetz and increase of crop yields. In detail it may adjust pH, depress alkalinity, reduce bulk density and compactness and increase water permeability and retention ability of the soil. Meanwhile agricultural use of furfural residue provided an effective way to avoid its pollution of the soil, Water and air.展开更多

There are various kinds from them, but all of them are going on work at highest temperature. There isn＇t a PEMFC which can run at room temperature, like 20 ℃. In this study there is a aim for constructing such one for alternative fuels utilisation. PS and many electroconducting polymer formulations were proved by different researchers for PEM benefications, but here PS was synthesized without containing metalic contaminants and after converted to the PEM membrane.展开更多
